Strikes and shipping disruptions cut Kharg export throughput to about 5M bpd

Iran’s oil bottleneck just got a lot more visible. Kharg Island — the terminal that handles almost all of Iran’s crude exports — appears to have gone unusually quiet over the past several days. Satellite images showed no ocean-going tankers at the island on May 8, 9, or 11, which is the longest such stretch since the war began. ### Why does Kharg matter so much? Kharg is not just another port. It is the hub for roughly 90% of Iran’s oil exports, which makes it one of the most concentrated energy choke points anywhere in the world. Earlier this year, Kpler data showed Iran exporting about 1.7 million barrels a day, with roughly 1.55 million of that moving through Kharg. Before the war, Iran had pushed total exports up to about 2.17 million bpd in February. (bloomberg.com) ### What changed this week? The big change is not a formal shutdown notice. It is the shipping pattern. Bloomberg’s satellite review found no ocean-going tankers at Kharg on May 8, 9, or 11, and described that as the first prolonged halt since the war started. That does not prove the terminal is physically destroyed. But it does show exports are not moving in the normal way. (straitstimes.com) ### Is this about strikes or shipping risk? Basically, both. Kharg had already become a military flashpoint in March, when U.S. forces struck military targets on the island and Washington openly threatened Iran’s oil infrastructure if shipping interference continued. Even when oil facilities were not directly hit, the market was already watching for pipeline, storage, loading, and marine-access disruptions. Once tankers stop showing up, the distinction between “infrastructure damage” and “shipping risk” matters less in practice. (bloomberg.com) ### What about the oil spill? That is part of why nerves are so raw. Reuters-reported satellite imagery showed a suspected oil slick west of Kharg between May 6 and 8, covering dozens of square kilometers. The cause was unclear, and images from May 8 reportedly showed no sign of an ongoing active leak. Still, an oil slick near the main loading hub adds one more sign that operations around the island are under stress. (straitstimes.com) ### How big is the market risk? The immediate risk is not that 5 million bpd vanished overnight from global supply — that figure looks more like a notional throughput or handling-capacity discussion than Iran’s recent actual exports. The real, verified number is smaller but still important: around 1.55 million bpd had been moving through Kharg earlier this year. Losing or delaying that volume would still tighten an already stressed market. (arabnews.com) This is especially true because Hormuz disruption amplifies every local outage. ### Why does Hormuz make this worse? Because Kharg sits upstream of the Strait of Hormuz crisis, not outside it. If tankers cannot safely approach, load, or transit, Iran’s exports back up fast. And if Iran feels cornered, the risk shifts from lost barrels to wider maritime escalation — attacks on shipping, retaliation against regional energy assets, and insurance costs jumping across the Gulf. That is why traders care even when the physical damage picture is still blurry. (straitstimes.com) ### So what should you watch next? Watch for tankers returning to Kharg, not just headlines about strikes. If ships resume loading within days, this looks more like a severe interruption than a lasting outage. If the jetties stay empty, then Iran’s main export artery is effectively partially shut — and oil prices, freight rates, and naval risk in the Gulf all stay under pressure. (straitstimes.com) The bottom line is simple. Kharg is Iran’s oil choke point. Right now, the clearest evidence says flows there have stalled for several days. That alone is enough to make this more than a local disruption. (bloomberg.com)
